RHEL 8 Deprecated Network Scripts
From your first link:
Note that custom commands in
ifdown-localscripts are not executed.
If any of these scripts are required, the installation of the deprecated network scripts in the system is still possible with the following command:
~]# yum install network-scripts
So, anything contained in the RHEL 8
network-scripts RPM file or relying on functionality of that RPM is now deprecated. In particular, if you previously used scripts like
/sbin/ifup-local to set up some advanced routing or other specialized network configuration, now it's time to find out a new way to do that.
Note that when NetworkManager was introduced into RHEL, it included - and still does - a configuration back-end that uses the old configuration file locations, but with a new NetworkManager infrastructure and an extended version of the old configuration script syntax. So the
/etc/sysconfig/network-scripts/ifcfg-* files will still be there and using the same syntax, although they will now be parsed by NetworkManager and not executed as sourced scripts.
network-scripts package essentially contains:
- the SysVinit-style service script
network-functions*scripts you've used to seeing in the
- classic versions of
/usr/sbin/ifdown(which would override the compatibility wrappers for
nmclithat are present by default)
- and the associated documentation and example files
So, when you're not using the deprecated
network-scripts RPM, you would now expect the
/etc/sysconfig/network-scripts/ directory to only contain the
ifcfg-* files for your network interfaces, and possibly
route-* files for custom routes, but no other files at all. If you needed the
usernetctl command, it's among the deprecated functionality and you should start using the appropriate
nmcli subcommands as its replacement.
ifdown will still be available, but now do their job through
NetworkManager, unless you install the deprecated
